Objective To report the early mortality and associated risk factors after damage control operation (DCO) in patients with severe abdominal trauma.Methods A total of 146 patients hospitalized from January to March in 2015 were retrospectively analyzed.Early death was defined as death occurring within 72 h of first surgery and before the definitive surgery.Based on the death definition, the subjects were divided into death group and survival group.The two groups were compared for gender, age, injury time, injury classification, vital signs, need for cardiopulmonary resuscitation, Glasgow coma score (GCS), injury severity score (ISS), hemoglobin, platelets, prothrombin time (PT), activated partial thromboplastin time (APTT), blood pH, base excess, operative time, and postoperative acute physiology and chronic health evaluation score Ⅱ (APACHE Ⅱ).Logistic regression analysis was applied to examine the predicators of early postoperative mortality.Results There were 118 patients (80.8％) in survival group and 28 patients (19.2％) in death group.Survival and death groups differed significantly with regard to the percent of elderly (6.8％ vs.21.4％), percent of patients with multiple injury (62.7％ vs.85.7％), body temperature [(36.1 ± 0.4) vs.(35.2 ± 0.8) ℃], percent of patients with greater ISS (31.4％ vs.64.3％), PT [(12.1±1.5) vs.(13.9±1.2)s], bloodpH (7.25±0.04vs.7.08±0.11), base excess [(-8.9±2.8) vs.(-10.6±3.3)mmol/L], postoperative APACHE Ⅱ[(12.8 ± 1.8) vs.(17.5 ± 2.0) points] (P ＜ 0.05).Logistic regression analysis identified the age (OR=1.512, 95％ CI 1.112-4.157,P＜0.05), ISS (OR =1.313,95％ CI 1.134-5.442, P ＜ 0.05), APACHE Ⅱ (OR =1.361,95 ％ CI 1.182-5.222, P ＜ 0.05) as the independent risk factors for early mortality.Conclusion The patients underwent DCO for severe abdominal trauma has a high early mortality, which is closely associated with the age, injury severity and postoperative medical status.

Objective To analyze the result of late course accelerated hyperfractionation (LCAFR) and three dimensional conformal radiotherapy plus concurrent chemotherapy (LCAFR+C)on stage Ⅲ esophageal carcinoma. Methods Ninety-eight patients with stage Ⅲ esophageal carcinoma were divided randomly into two groups:1. LCAFR group: patients were treated with conventional fractionated radiotherapy during the first two-thirds of the treatment to a dose of 40?Gy in 20 fractions over 4 weeks, then followed by LCAFR with reduced fields using three dimensional conformal radiotherapy to a dose of 15-24?Gy over 7-12 days, 1.5Gy per fraction, to the total dose of 55-64?Gy in 30～36 fractions over 35-40 days. 2. LCAFR+C group:The radiotherapy schedule was the same as the LCAFR group,but with concurrent chemotherapy of DDP 20?mg d1-5, LF 200?mg and 5-Fu 500?mg d 6-10 , 28 days in one cycle to totally 5 cycles. Results The 1-, 2-, and 3-year actuarial survival rates were 73%, 53%, 35% and 76%, 73%, 55% respectively (? 2=4.12,P

0.05).But aripiprazole produced fewer side effects than risperidone,such as extrapyramidal symptom,gain weight,disorder of menstruation.Conclusion:Aripiprazole is as effective as risperidone for the treatment of the initial schizophrenia and has fewer side effects.

ObjectiveIn order to study the effect of three-month rehabilitation on motor function in hemiplegics after stroke. Methods125 patients were randomly divided into two groups, rehabilitation group (72 cases)and control group(53 cases).Patients in the rehabilitation group were given clinical treatment,electric stimulation therapy(EST) and regularly physical therapy, while those in control group were given clinical treatment and unguided self-training, and the evaluation was done in pre-treatment and post-three-month respectively. Motor function was assessed in Fugl-Meyer Assessment(FMA).ResultsMotor scores in each group had a more significant difference(P<0.001)before and after treatment, the process of scores in the rehabilitation group was obviously superior to that in the control group(P<0.001). Conclusions Rehabilitation training on hemiplegics after stroke may obviously improve motor function, depressing the disability and increasing the living quality.

Objective:Through a study on knowledge, attitudes, and practice of tobacco control of medical staff in Gansu Province, the paper aims to analyze the issues of participation, community tobacco control leadership and other aspects that impact the creation of a smoke-free healthcare system in order to provide a basis for the formulation of policies to improve the health professional mechanism of tobacco control. Methods:The stratified cluster sampling method was adopted to select 34 companies, accounting for a total of 805 medical staff as the study population in all kinds of health institutions. A self-designed questionnaire was adopted to investigate their knowledge, attitudes, and practice via on-site self-administered surveys. Results:the medical staff lacks knowledge as to the depth and breadth of damage from the use of tobacco. Although their attitude towards tobacco control is positive, the comprehensive to-bacco control service capabilities are insufficient. Logistic regression analysis showed that tobacco control capabilities of medical staff is related to their attitude toward smoking and whether or not they discourage smoking or asking about smoking . Conclusion:The key to the creation of a smoke-free health system to lead the community in tobacco control is the targeted tobacco cessation knowledge and skills training of medical staff to reduce smoking rates among medical staff and enhance the awareness of administrative staff.

Purpose To reconstruct perfusion computerized tomography angiography (PCTA) images from the volume data of low-dose brain CT perfusion scan with iterative reconstruction algorithm, to analyze the capability of PCTA on the display of brain arteries, and to explore the methods to reduce the radiation dose for stroke CT examinations. Materials and Methods This was a prospective study, 55 patients (605 arterial segments) with clinical diagnosis of ischemic cerebrovascular disease underwent cranial CT scan, iterative algorithm low-dose brain CT perfusion scan and conventional cranial CTA examinations using a 256-slice spiral CT. 11 segments of the cerebral artery in each case were analyzed using conventional CTA results as the reference standard to assess the display of brain arteries in PCTA. Results Effective dose of CT perfusion scan was 2.12 mSv. Among the 580 vessel segments which CTA showed no stenosis or stenosis<30%, only one vessel segment of PCTA was inconsistent with CTA; among the 19 vessel segments which CTA showed stenosis≥30%but not occluded, results of 12 vessel segments in PCTA were consistent with CTA, while the stenosis states were exaggerated by PCTA in the other seven vessel segments;results of the two methods were consistent in six vessel segments which was found occluded by CTA. Kw values were >0.75 for the consistency test between PCTA and CTA on the display of brain arteries. Conclusion Radiation dose of iterative algorithm cranial CT perfusion scan is significantly lower, and the images reconstructed from the volume data of perfusion CT are highly consistent with the CTA results, thus are able to meet the needs of the clinical diagnosis.

Objective To assess the enhancement feature of intracranial atherosclerotic plaque in the vessel supplying the territory of infarction by using high-resolution MR imaging.To analyze the correlation between the degree of plaque enhancement , time elapsed and the concentration of hypersensitive C-reactive protein ( hs-CRP ).Methods The characteristics of vessel walls and intracranial vascular stenoses were retrospectively analyzed in 81 patients with ischemic strokes.All subjects were imaged with a traditional stroke MR protocol and HR-MRI scanning for plaque on a 3.0 T MRI scanner.According to the elapsed time between infarct and MR examination , all cases were classified into early stage (<4 weeks from acute stroke, n=58), middle stage (4-12 weeks, n=13) and late stage ( >12 weeks, n=10).The characteristics of vessel walls and degrees of enhancement of atherosclerotic plaques were assessed and the concentrations of hs-CRP in all patients were determined.The Kruskal-Wallis H test was used to compare the degree of enhancement and hs-CRP concentration among the early , middle and late stage.The concentration of hs-CRP was presented as median ( interquartile range ).The Spearman correlation was used to analyze the correlation between elapsed time , hs-CRP concentration and degree of enhancement.Results Fifty-five (55/81) plaques were located at the M1 segments, and the other 26 (26/81) plaques were at the basilar artery.The degree and presence of enhancement from strong to none were 29, 25 and 4 in the early stage;4, 6 and 3 in the middle stage and 0, 4, 6 in the late stage, respectively.The degree and presence of enhancement were significantly different among them (H=16.934,P<0.01).There was a remarkable trend of decreasing degree and presence of enhancement of the atherosclerotic plaque relative to increasing time after the ischemic event(r=-0.792,P<0.01).The serum hs-CRP concentration for early, middle and late stage were 7.0(3.0, 13.0), 2.27(1.0, 3.03) and 1.88(0.50, 4.0)mg/L (H=14.345,P<0.01) , respectively.There was a trend of decreasing hs-CRP concentration relative to the time elapsed ( r =-0.357,P<0.01).The degrees of enhancement of the plaques were parallel to the levels of hs -CRP( r=0.526,P<0.01).Conclusions Enhanced HR-MRI scanning may clearly demonstrate the enhancement characteristics of intracranial atherosclerotic plaques as an indicator of inflammation.It might play an important role to detect risk factors for intracranial plaque rupture and subsequent acute ischemic stroke .

Objective To evaluate whether the protein SP70 could be used as a serum biomarker for the diagnosis of non-small cell lung cancer (NSCLC).Methods Polyclonal antibody was prepared by immunizing New Zealand rabbit with SPC-A1 cells.Sandwich ELISA was carried out by using newly-prepared polyclonal antibody(PcMb) coating assay plates,monoclonal antibody (McAb) NJ001 and HRP goat antimouse antibody as primary antibody and labeling antibody respectively.After optimizing the experiment conditions,serum from 175 lung cancer patients [ 80 NSCLC adenocarcinoma,70 NSCLC squamous carcinoma and 25 small cell lung cancer ( SCLC) ],25 benign lung disease ( BLD) patients and 300 healthy controls (HC) were examined.CEA,NSE,CYFRA21-1 were measured by ECLIA for comparison.Results Positive rates of NSCLC adenocarcinoma,NSCLC squamous carcinoma,SCLC and BLD were 68.8％,51.4％,16.0％ and 12.0％ respectively,obviously higher than that of HC (7.3％).NSCLC (adenocarcinoma,Squamous carcinoma) had significantly higher positive rate than SCLC (60.7％ υs 16.0％,x2 =17.23,P＜0.05)and BLD(60.7％ υs 12.0％,x2 =20.41,P ＜0.05).Among 68 NSCLC patients who had definite staging,positive rates at early stage ( Ⅰ/Ⅱ,n=30) reached up to 76.7％.Meanwhile,positive rates of CEA,NSE and CYFRA21-1 (32.7％,18.0％ and 37.3％) were significantly lower than the targeting antigen to McAb NJ001 in NSCLC(60.7％ υs 32.7％,x2 =23.63,P ＜0.05;60.7％υs18.0％,x2 =57.22,P＜0.05;60.7％ υs37.3％,x2=16.34,P＜0.05).Conclusions It showed high positive rates of SP70 in the serum of NSCLC patients,which suggested thai SP70 might be a potential valuable biomarker for the diagnosis of NSCLC.

Objective To investigate the diagnostic value of detection of protein SP70 in differentiating benign and malignant pleural effusion.Methods A case-control study was conducted from July 2011 to February 2012.108 cases of pleural effusion from patients with clinically proven lung cancers and 122 cases of benign pleural effusion were collected.SP70 was detected by Sandwich ELISA,while CEA,CYFRA21-1,NSE were measured by electrochemiluminescence immunoassay for comparison.Meanwhile,protein SP70 on exfoliated cells in pleural effusion was detected by direct immunofluorescence,and was compared with the results of HE staining.The differences between the groups were evaluated by the chisquare test Fisher' s exact test.Results Positive rates of SP70,CEA,CYFRA21-1,NSE were 72.2％,58.3％,52.8％ and 30.6％ in malignant pleural effusion,obviously higher than benign pleural effusio (9.8％,13.1％,23.0％ and 19.7％).The specificity of SP70,CEA,CYFRA21-1,NSE were 90.2％,86.9％,77.0％ and 80.3％,NSCLC had significantly higher positive rate than SCLC(74.3％ ＞0.0％,P =0.02 ＜ 0.05),detection of protein SP70 in malignant pleural effusion had significantly higher coincidence rate than HE staining(72.2％ vs 47.2％,x2 =14.03,P ＜ 0.05).Conclusion Determination of the protein SP70 in pleural effusion and in exfoliated cells,can improve the sensitivity and specificity of the diagnosis of malignant pleural effusion.

Objective: To compare the diagnostic consistency and efficacy of arthroscopy and MRI on the severity of acute lateral ligament complex (LLC) injury, and to find an effective method to diagnose acute LLC injury accurately in early stage. Methods: Data of 37 patients (27 males, 10 females), with acute lateral ligament complex injury who were treated from February 2015 to December 2016 were retrospectively analyzed. The average age was 28.6±6.2 years (range, 18-42 years) and duration from injury to operation was 4.6±3.3 days (range, 0.3-8 days). The results of MRI and ankle arthroscopy for detecting LLC injury were compared, and the consistency between the two examination results was analyzed. Results: Different consistencies were found between the two examination methods according to different parts of LCC injuries. The consistency of injuries (partial tear,complete tear) at the starting point of anterior talofibular ligament and complete tear at the starting point of calcaneofibularliga-ment was ordinary (kappa=0.641, 0.624, 0.680), while the consistency of damage in other parts of LLC was poor (kappa< 0.4). Compared with arthroscopy, MRI has a diagnostic accuracy of 62% (23/37) for partial tear of anterior talofibular ligament, and 62% (23/37) for complete tear. And that of the calcaneofibularligament complete tear was 78% (29/37). Conclusion MRI had low capability in detecting the severity of acute LLC injury accurately and the diagnosing efficacy was insufficient, while ar-throscopic exploration had a high diagnostic value for acute ankle joint injuries.
